Driver Controls
• With vehicles that edge into your lane. These vehicles can only be
detected once they have moved fully into your lane.
• There may be issues with the detection of vehicles in front when
driving into and coming out of a bend or curve in the road.
In these cases ACC may brake late or unexpectedly. The driver should
stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false vehicle detections. Check with
your authorized dealer to have the ACC radar checked for proper
coverage and operation.

• The sensor is blocked, refer to Blocked sensor in this section.
